In this Arduino-based line adherent robot, we have utilized IR Transmitters and IR recipients likewise called photodiodes. They are utilized for sending and getting light. IR communicates infrared lights. At the point when infrared beams fall on the white surface, it’s reflected back and got by photodiodes which produce some voltage changes. At the point when IR light falls on a dark surface, light is consumed by the dark surface and no beams are reflected back, accordingly, the photodiode doesn’t get any light or beams. Here in this Arduino line adherent robot when the sensor detects white surface then Arduino gets 1 as information and when detects dark line Arduino gets 0 as information.
